• Uninterruptible Power Supply (UPS) systems

Battery Energy Storage Systems (BESS)

Power Monitoring Systems (PMS)

• Building Management Systems (BMS) and Electrical Monitoring Systems (EMS)
• Emergency Power Off (EPO) systems
• Earthing and lightning protection systems
• Data centre critical power infrastructure

Key Responsibilities

• Act as the Senior Authorised Person for electrical systems, managing and enforcing Global Commissioning's Safe Systems of Work.

• Review and approve Risk Assessments and Method Statements (RAMS) for electrical works.
• Plan, coordinate, and supervise HV/MV/LV switching activities.
• Oversee pre-functional testing, electrical energisation, protection testing, and commissioning readiness activities.
• Attend and contribute to commissioning, coordination, and safety meetings.
• Coordinate electrical commissioning activities with mechanical, controls, and automation teams.
• Attend and support Functional Performance Testing (FPT) and Integrated Systems Testing (IST) of critical systems.
• Carry out final inspections and "white glove" reviews prior to system handover.
• Ensure compliance with site safety procedures, electrical standards, and applicable legislation.
• Maintain effective communication between contractors, vendors, and client stakeholders.
• Support incident response, emergency situations, and high-risk operations when required.

Leadership & Management

• Provide leadership and supervision to electrical teams, contractors, and subcontractors.
• Manage complex and high-risk electrical activities in live or operational environments.
• Demonstrate strong decision-making under pressure, particularly during switching operations, isolations, energisations, fault conditions, and system reinstatements.
• Promote a strong safety culture and proactive hazard identification.
